SPECIFICATION forming part of Letters Patent No. 558,562, dated April21, 1896.

A li ti fil d December 31,1894. Serial No. 588,407. (No model.)

To all whom it may concern:

Be it known that I, ROBERT IV. PAIN, acitizen of the United States,residingin New York city, in the county and State of New York, haveinvented certain new and useful Improvements in Musical Instruments, ofwhich the following is a specification.

I will describe a musical instrument embod yin g my improvement, andthen point out the novel features in claims.

In the accompanyingdrawings, Figure 1 is a top view of the principalparts of a musical instrument embodying my improvement, the case beingwholly omitted and certain parts being shown in section. Fig. 2 is avertical transverse section of the same at the plane of the dotted linea (E, Fig. 1. Fig. 3 is a section a1 front elevation, the section beingtaken at the plane of the dotted line 1 y, Fig. 2. In this view certainparts are broken away. Fig. 4: is a horizontal section taken at theplane of the dotted line '2: c, Fig. 3. Fig. 5 is a top view of awindmotor comprised in the instrument. Fig. 0 is a vertical transversesection at the plane of the dotted lines .2 .2, Fig. 5, a

portion, however, intersected by this plane being shown in full sideview. Fig. 7 is an isometrical perspective view of one of a series ofvalves for controlling the sound-producing devices, said valves beingrepresented as having component parts separated for the purpose ofillustrating their construction. In this view parts comprised inadditional valves are indicated by dotted lines. Fig. 8 is a sectionalplan taken upon a reduced scale, as indicated by dotted lines 20 20,Fig. 2. Fig. i) is a view taken parallel with the front of theinstrument and illustrating mechanism for winding 21 music-sheet. Fig.10 is a vertical section, parallel with the front of the instrument, ofa tracker-board over which a perforated music-sheet is intended totravel. Fig. 11 is a top view of this tracker-board. Fig. 12 is ahorizontal section taken at the plane of the dotted lines a u, Fig. 10.

Similar letters of reference designate correspondin g parts in all thefigures.

A A A A designate sound-producing devices. In thepresent example of myimprovement these sound-produein g devices consist of reeds, and thereare four banks of these reeds.

The reeds are arranged in cells 13 13 13 13", which maybe of ordinaryform and controlled by mutes O C 0 0 These mutes may be operatedseparately by ordinary stop-rods G to bring into use any one or more ofthe banks of reeds, or they may be all operated by one contrivanceas,for instance,by a stop-rod As I do not claim anything in themechanism whereby the different stops are enabled to control the mutesseparately, I shall not further describe such mechanism.

Preferably the device which is employed to operate all the mutes, andwhich in the present instance consists of the stop 0 will be so combinedwith the mutes as to operate them successively instead of operating themall to gether. The mechanism for accomplishing this I will now describe,premising that it is best illustrated in Figs. 1, 2, and 3. To the rearend of the stop-r0d G is pivotally connected a rod 0", which is alsoconnected with an arm 0, that extends radially from a rockshaft 0".Affixed to this rock-shaft are two sets of cams 0 each set being of anumber corresponding to the number of mutes. These cams may be ofsimilar shape, but they are arranged upon the rock-shaft, so that onewill act slightly in advance of the other. They coact with a number oflevers C, which rest upon their upper surfaces. These levers C connectwith upright rods of ordinary construction, and the latter in turn areconnected with the ends of the mutes, so that each mute will be shiftedby power applied to both its ends. The only feature of importance inthis connection is the one consisting of the mechanism which, by forceapplied to a single draw or stop rod, will raise all the mutes, but willdo so one after the other.

While on the subject of the stop-rods it may be well to explain that arod C which is similar in construction and operation to the stop-rods 0,controls the direction of movement of the wind-motor, which is employedin the instrument to move the perforated music-sheet, and consequentlythe direction of the movement of said sheet. This rod C is combined withthe stop-rods C, so that if any one of the stop-rods C is pulled out therod C will be automatically moved in and conversely, so that each timethat the rod 0' is moved outward the stop rods will be moved in. This isquite an important feature, because it is necessary to pull out the redC after playing a piece of music in order to cause the music-sheet to berewound upon the music-roll, and it often happens with instruments ofordinary construction that the rod 0 is left out after the introductionof another sheet of music and the pulling out of stops preliminary toplaying. Thus a sheet of music which has been attached to the takeuproll will often be detached and necessitate the trouble of reattaehingit. As it is necessary to pull out one of the stop-rods before anyplaying can be done, it is obviously advantageous that the act ofpulling out the stop-rod will return the rod 0 to its normal position.The means here shown for combining the stop-rods with the rod 0 comprisea bar C, which extends across the stop-rods and is connected by links 0to a stationary part C of the instrument. In the present instance thebar 0 lies on top of the stoprods rearward of the stop-board 0 which isa board through which the stop-rods pass. Preferably the bar 0 will befaced with felt or other soft material on the under side. The links 0are pivotally connected at one end to the bar 0 and at the other end tobrackets extending from the stop-board 0 From the stop-rods in the rearof the bar 0 extend pins 0 which preferably will be fitted withantifriction-rollers. These pins are so spaced that when the stop-rodsare pulled out said pins will be moved adjacent to the bar C. The pins 0do not contact with the bar 0 except when the bars are pulled outward.At one end the bar 0 is pivotally connected with one arm of a bell-cranklever 0 which is fulcrumed at the middle to a bracket extendingrearwardly from the stopboard 0 and at the other end is forked to engagewith a pin 0 extending from the rod 0 It is obvious that if any of thestop-rods C occupy their outer positions at the time that the rod C ispulled outwardly the outward movement of the latter will, through theagency of the lever 0, shift the bar 0 in such manner that the latterwill, by acting against the pins 0 of such stop-rods, force thesestop-rods inward. It will also be seen that if the rod C is left in itsouter position at a time when one of the stop-rods C is pulled outwardthe pin 0 of the latter will shift the bar C, so as to rock the lever Cin the proper manner to force the rod (3 inward.

Besides the stop-rods O and the similar rods C 0 there is a rod 0 whichis similar in construction and operation. This is connected by a radialpin 0 with a bell-crank lever C which is fulcrumed between its ends to abracket extending rearwardly from the stopboard C connected with a rod 0that serves to control the wind-motor before mentioned, as will beclearly explained when describing the motor and its appurtenances.

The musical instrument which I have chosen to illustrate the improvementis provided with .main portion, so as to form journals.

a keyboard and so constructed that the soundproducing devices may beplayed either manually or mechanically under control of the perforatedmusic-sheet. The organization is such that all the banks of soun d-producin g devices may be played either manually or mechanically. To preventthe accidental operation of a key while the instrument is being playedmechanically, it is desirable to provide means whereby the function ofthe keys may be suppressed during the mechanical playing of theinstrument. For this purpose there is a rod C", which is similar inconstruction and operation to the stop-rods 0. Connected to it is a rodC, that extends to a rocking bar 0. The latter is bent transversely nearits ends and at the extreme ends is bent parallel to its y rocking it inone direction the main portion will rise under the keys. This isaccomplished by the drawing out of the rod 0 A reverse movement of therod 0 will lower the rod G and leave the keys free to be used. It may beadded here, although in anticipation of what will be more fullyexplained hereinafter, that the inward movement of the red 0 applies acover K to the tracker-board L, over which the perforated music-sheetadvances.

I will now describe the valves D, which immediately control the speakingof the reeds. Their construction may be best understood by reference toFig. 7 but they are also illustrated in Figs. 1, 2, and 3. Each of thesevalves comprises a block (Z, in one face of which is formed a channel d,which is cov ered by a strip of flexible material (1 that may wellconsist of leather. The chamber thus formed is closed at the top by aportion (1 of the action-frame, as may be seen at Fig. 2. The bottom ofthis chamber communicates with a duct (P, which whenever it is desirableto cause a speaking of the corresponding sound-producing devices is putin communication with the wind-inducing apparatus of the instrument, themusic-sheet being the device which controls the action of such duct. Thewind apparatus and various devices which are intermediate of themusicsheet and the said duct I will presently describe in detail.

I have said enough to make it clear that at times eachcl1amber,consistin g of a channeled block 61 and strip of flexiblematerial (P, will be put into communication with the wind-inducingapparatus. The musical instrument illustrated by the drawings isintended to have exhaust-bellows, and therefore whenever one of thesechambers I) D D is put into communication with a duct d its flexiblestrips (P will be forced into the channel d. hen this happens, air ispermitted to pass the outer side of the flexible strip (1 (not that sidewhich is toward the channel (1) to cause the speaking of the reed. Tocontrol the passage of air necessary for the speaking of a reed, eachflexible strip (1 coacts with abridge or rib (Z IOC IIC

As here shown, the back of each block (Z (by this I mean the unchanneledside) has a bridge or rib d formed vertically upon it. At each end ofthe bridge or rib the block has a transverse extension (2, and thesetransverse extensions of each block fit against the flexible strip (Z ofthe next adjacent block.

Behind the valves D is a win d-chest E, which is in communication withthe wind-inducin g apparatus. Vhenever one of the flexible strips d of avalve D is drawn into the channel (1 of said valve, it will leave the opposite bridge or rib (Z of the next adjacent valve D, and thus establishcommunication between the wind-chest E and the cell of the reed whichcorresponds to the thus actuated valve. Assuming that the mute of suchcell is open, atmospheric air will thus be induced to flow through thereed to the windchest E.

It may be well now to describe the windinducing apparatus.

F designates exhaust-bellows, which may be operated in any suitablemanneras, for instance, by ordinary pedals. I have only shown a strap fas the means for operating one of these bellows. It may extend to anysource of power. Of course there may be any desirable number ofexhaust-bellows, and they may alternate in their operation as usual.

F is an equalizer, which, as usual, is made in the form of a largebellows, f being its expansible side. This equalizer communicates bymeans of a duct or ducts f with a windchest G. For the sake of clearnessit may be well to call the wind-chest G the main wind-chest and thewind-chest E the windchest for the sound-producing devices.

II designates a chamber capable of collapsing and expanding more orless. It is shown as made of bellows-like construction, but it has novalves. It is in communication with the wind-chest E for thesound-producin g devices. As here shown, the chamber II communicatesdirectly with a chamber II, and the latter communicates with a trunk Hwhich opens into the wind-chest E for the sound-producing devices. Thischamber II is shown as arranged below the wind-chest G and ascommunicating with the wind-chest G through one or more holes 9 in thelatter. For each hole 9 there is in the chamber 11 a valve 71 which hereshown hinged in place at one end and pressed upwardly by a spring 7L.The free end of the valve is connected in any suitable manneras, forinstance, a flexible connection W-with the movable part of the chamberII. The connection between the valve h and the movable part-of thechamber II is to be such that when the chamber II is collapsed to thefull extent the valve 71. will reach its scat an d close the oppositeopenin g.

I designates a chamber capable of being collapsed or expanded more orless and made, as here shown, in the form of a bellows, but withoutvalves. It is in continuous communication with the wind-chest G.

The movable part of the chamber II is connected with the movable part ofthe chamber I in any suitable manneras, for instance, by rods J,extending outside the chambers and the windchest G and connected withthe movable parts of such chambers. I/Vhenever the tension of the airwithin the wind-chest G is sufficient to collapse the chamber II to thefullest extent, the valve or valves h will close the opening or openingsg. Thereupon the communication between the chamber H and the windchest Gwill be cut off. The upward movement of the movable part of the chamberII due to the collapsing of this chamber will raise the movable part ofthe chamber I, and as this chamber I is continuously in communicationwith the wind-chest G said chamber I has a tendency to collapse. Thistendency is exerted through the action of the rods J upon the chamberII. WVhenever it preponderates, it will open the valve or valves h andthus establish communication between the chamber H and the wind-chest G.This action will occur almost continuously, although it will beintermittent, and owing to this the valve or valves h will vibrate toand from the opening or openings 9 almost constantly. As the chamber His in communication with the wind-chest E for the sound-producingdevices, there will always be a diiterent tension in the latterwind-chest from what there will be in the main wind-chest.

It is veryimportant to provide for one tension of air for thesound-producing devices and a different tension for the other parts as,for instance, pneumatic valves and pneumatics generallyfor in this waythe pneumatic valves and pneumatics may be operated with air undergreater tension than would be suitable for sound-producing devices. Insome musical instruments it is very advantageous to operate some of thesound-producing devices by air under different tensions, and thisfeature of the present improvement provides for that as well as for adifferentiation of the air-tension employed to operate pneumatics.

The improvement also comprises means whereby the differentiation ofair-tension in parts of a musical instrument may be varied at will.Obviously in the apparatus illustrated in the drawings any force appliedupwardly to the movable part of the chamber I will oppose the action ofthe wind-chest G upon this chamber I, and hence will tend to change theamount of tension which otherwise would be exerted by the chamber I uponthe wind-chest G. Force may be applied upwardly to the movable part ofthe chamber I by any suitable mechanical means. In the present instanceI have shown the movable part of said chamber as connected to a strap I,which is wound around a rock-shaft 1 that is supported in brackets 2" tFrom the forward portion of this rock-shaft extends an arm and thiscoacts with the knee swell or lever 1 the latter being pivoted by a pini to a fixed rail i of the instrument. Obviously by moving theknee-swell out of its normal position the rock-shaft I may be made towind up the strap I and thus raise the movable part of the chamber I.Many other arrangements might be employed, without departing from theinvention, for exerting an opposing force to the wind-chest Gr upon thechamber I.

The perforated music-sheet has not been illustrated, because it is ofordinary construction. The music-roll is intended to be supportedbetween brackets M. In one of these brackets there will be a shaft thatwill engage the music-roll.

N designates the take-up roll, to which the outer end of the music-sheetis attached. The music-sheet is drawn along by this take-up roll duringthe playing, and at such time the shaft previously mentioned as engagingwith the music-roll runs freely. After the playing a change ofconnections may be made, so as to allow the take-up roll to run freelyand so as to simultaneously impart motion to the music-roll through theshaft with which it is engaged. The mechanism for accomplishing this maybe of ordinary construction.

In Fig. 9 I have shown that the take-up roll N is provided at one endwith a gear-wheel n, which en gages with a pinion 72, mounted upon ashaft N which is supported in a rocking frame N, the latter beingpivoted at n and normally pressed upwardly by a spring a for the purposeof engaging the pinions 'n, with the gear-wheel 01. On the shaft N isaffixed a pulley N and this is belted to the windmotor. Loosely mountedupon the shaft N is a pulley N, and this is belted to the aforesaidshaft which is engaged with the musicroll. The pulley N is capable ofmovement lengthwise with the shaft N and is provided with a clutch-pieceor, which, upon a movement of the pulley lengthwise of the shaft N maybeengaged with or disengaged from a clutch-piece n that is aflixed to theshaft N A bell-crank lever N engages with a circumferential groove inthe clutch-piece of the pulley N and serves to move it lengthwise of theshaft N This lever N is fulcrumed to a pin 42 which is supported by astationary bracket and is pivotally connected by a pin a with therocking frame N. The latter has a pin a over which extends a lever N.This lever N is fulcrumed by a pin a to a station ary bracket, and atthe free end is connected to a rod N which is operated whenever the rodO is manipulated. It will thus be seen that the rod 0 determines thedirection in which the perforated music-sheet shall be driven.

The tracker-board L may advantageously be made of three sections, asshown in Figs. 10, 11, and 12, for in this way small perforations may beused in the music-sheet, and consequently the width of the music-sheetmay be less than otherwise would be necessary, and yet the ducts may bemade sufficiently capacious to afford a free passage of air from themusic-sheet. It will be seen that the tracker-board is made of threetriangular sections, the center one Z being provided with narrowvertical ducts Z, and the other sections Z Z being provided with oblique ducts Z, which are considerably larger. The divergence orspreading of the ducts accomplished in this way compensates for thedifference in width of the music-sheet and the banks of sound-producingdevices with the appurtenances of the latter. The ducts Z communicatewith ducts Z in a horizontal board L. The ducts Z may be parallel, andthe forward ends are extended beyond the board L and are provided withopenings which are controlled with valves 0 operated by manual keys. Thecover K, previously mentioned, is pulled down over the tracker-board Lwhen the instrument is to be played man-.

ually, thus suppressing the action of the tracker-board L. At the sametime that the cover K is pulled down upon the trackerboard the rod C islowered, so as to permit of the operation of the keys. As alreadyexplained, when the cover K is raised from the tracker-board, so as topermit of playing the instrument mechanically, the rod O is raised so asto suppress the keys.

The ducts Z communicate at their rear ends with vertical ducts Z and aboard L Above the board L there is a block L which is provided withvertical ducts Z", corresponding to and communicating with the ducts Zand hence with the ducts of the tracker-board. The ducts Z terminate attheir upper ends in chambers Z there being one for each duct. Each ofthese chambers Z is fitted with a flexible diaphragm Z on the other sideof which is a wind-chest L which is common to all of the diaphragms ZEach chamber Z communicates through a port Z with the chamber L.Preferably such port will be provided with a regulating device-such, forinstance, as a screw Z There is a duct cZ' corresponding to every ductof the tracker-board, and thus corresponding to every duct Z in thechambers Z Each duct (Z communicates with a separate chamber (Z Eachchamber cZ' has an opening d communicating with the atmosphere, and anopening CZ", communicating with the windchest L In each chamber (Z aretwo valves (Z CZH, fastened to a single rod 61 which is secured to thecorresponding diaphragm Z Each time that one of the ducts of the tracker-board L or the board L is open, air will pass to the correspondingchamber Z and force the diaphragm Z of such chamber toward theWind-chest L. This will cause the corresponding valve (Z to close theport (Z leading to the atmosphere, and to open the port d leading to thechamber D. Thus the corresponding valve D will be operated and thecorresponding sound-producing device caused to speak. l/Vhen a port inthe trackerboard L or board L is closed, the corresponding diaphragmwill be reversely operated and the corresponding valve D will be cut offfrom communication with the chamber I; and put into communication withthe atmosphere. This will cause the corresponding valve D to close andstop the speaking of the soundproducing devices.

The wind-chest Ir communicates with a pipe or duct L which passes acrossthe trunk II without communicating with it, and terminates in a trunk LThis trunk L communicates with a pipe L which passes through the chamberII without communicating therewith and extends into the wind-chest G.Consequently the chamber I is constantly subject to the air of greatertension.

\V designates the wind-motor. It is in communication with the wind-chestG by means of a pipe XV, but this pipe IV does not pass directly to themotor, but, on the contrary, to aregulating-valve box W containing aslidevalve IV, with which the rod c coacts. By manipulating the rod C inthe stopboard the valve may be shifted to vary the communication of thebox W with the wind-chest G.

The construction of the valve is immaterial. In the present instance itis rigidly affixed to its stem, and the latter is connected to a rod 10,against which the rod c, or an appurtenance thereof, acts.

It will be understood, of course, that as the valve-box IV is incommunication with the wind-chest G it is subject to air of greatertension.

The valve-regulatin g box IV communicates with the wind-chest 10* of themotor W. This wind-chest is of course in the present instance anexhaust-wind chest.

The motor XV comprises any desirable 11 umber of double collapsible andexpansible chambers "[0 Each is of bellows-like construction and hasthree boards, two of which are fixed, the third being arranged betweenthe two fixed boards and being movable between them. The two fixedboards are fastened to two opposite portions 21: a of a trough-shapedblock w w Q08. Each of the chambers 20 has a separate port 10 in theblock 20 10 10 Each of these ports extends from its chamber 10 downthrough the portion to of the block 10 10 w and then horizontallythrough the portions 10 w of said block. Each of the chambers 20 at theother side of its movable board communicates with a horizontal port inThe ports to w belonging to each chamber 20 have combined with them avalve 20, which is here shown as made in the form of a slide-valve andlarge enough to cover the outer ends of both ports to" 21: Such valvehas a chamber in its interior. Op-

posite the wind-chest in a port 10 extends to the outside of the block,there being one of these ports for each of the chambers 10". Each valve10 may either cut off its two ports 10 10 or establish communicationbetween either of these ports and a port 10 leading to the wind-chest1.1:.

When it establishes communication between one of the ports 20 ru and thewind-chest w, it opens the other port to or w to the atmosphere. Byalternately changing the communication of the ports to" 10 with thewind-chest w and with the atmosphere, the movable board to each cham berto will be made to move first in one direction and then in theotherbetween the fixed boards. Each ehamberu has pivotally connected toits movable board a bifurcated rod to, which is also connected with anarm w, extending from a shaft in. On the shaft 10 is a pulley 111 whichis belted to the pulley N before described. The crank-arms w may be setat an angle of one hundred and twenty degrees or in any other suitablerelation, so as to cause the movable boards of the chambers 10 tooperate in succession.. A rod to is pivotally connected at one end withthe crank w belonging to each chamber 10 and at the other end with thevalve to belonging to such chamber, and hence constitutes a means forshifting such Valve.
